Tremor

Tremor by the Xiph.Org Foundation is a fixed-point version of the Vorbis decoder for those platforms without floating point operations.

It is a software library that decodes the Vorbis audio format. It is free software released under the New BSD license. Tremor uses fixed-point and movable-point arithmetic numeric representations in its implementation so that it can be used by small embedded devices, which typically do not have floating-point processors. Thus, Tremor enables small embedded devices to play audio files stored in the Vorbis format. Tremor was originally developed by Xiph.Org as a part of a contract for the Iomega HipZip,[citation needed] but was since opened up to encourage wider use of the Vorbis format. Almost all hardware devices[clarification needed] that can play Vorbis, and many software implementations on embedded devices (such as mobile phones) use Tremor or some descendant.

Xiph.Org has expressed interest in modifying Tremor into a floating-point version, which would replace the current floating-point reference decoder, after the release of libogg2.[1]
